Adjustable arm: The float valve features an adjustable arm that can be set over 180 degrees to accommodate various water levels. No power source or pump required; hand-tight design ensures leak-free operation. High-Quality Material: The mini float valve with adjustable arm is constructed from high-quality plastic and brass, offering enhanced stability, resistance to rust, and reliable water inlet control for improved performance. Dimensions: The float valve uses 1/2 NPT pipe threads, commonly used in plumbing applications, with approximate thread size of 1/2 inch and standard washers to prevent leaks. Offers broader applicability compared to traditional metal float valves. Wide range of applications: Suitable for use in ponds, chicken coops, livestock watering tanks, aquariums, aquaponics, aquaculture, and hydroponic reservoirs. Provides greater adaptability than conventional metal float valves. Packing quantity: 2-pack of water tank float valves designed to reduce water filling time and minimize maintenance. Features a compact float control mechanism capable of withstanding higher fluid pressures with effective sealing performance. Operates on the principle of float ball water level control to regulate water inlet and outlet, maintaining a consistent water level, ensuring sufficient water volume, and promoting clean water conditions. Helps reduce cattle drinking water waste by over 30%, contributing to lower wastewater discharge.
